This study investigated two issues: the level of weight and shape concerns, and the self-reported tendency to eat in response to negative emotions among obese individuals with binge eating disorder (BED), eating disorder not otherwise specified (EDNOS), and no eating disorder (CONTROL).
On the basis of demographic and diagnostic surveys, 156 participants in a weight loss program were categorized on two dimensions, eating disorder category and weight (BED vs. EDNOS vs. CONTROL/low vs. high body mass index), yielding a 2 x 3 experimental design.
Individuals with BED reported a greater tendency to eat in response to negative mood states than CONTROL subjects and low weight EDNOS subjects, but not high weight EDNOS subjects. Weight did not influence self-reported weight and shape concerns. Individuals with BED expressed greater concern for weight and shape than non-eating disordered CONTROLs.
The findings suggest that overconcern with weight and shape be further investigated as a diagnostic feature of BED and that emotional eating is associated with BED but not obesity per se.
本研究探讨了两个问题:体重和体型关注程度,以及在患有暴饮暴食症(BED)、未特定的进食障碍(EDNOS)和无进食障碍(对照组)的肥胖个体中,自我报告的因负面情绪而进食的倾向。
根据人口统计学和诊断调查,将参加减肥计划的156名参与者在两个维度上进行分类,即进食障碍类别和体重(BED与EDNOS与对照组/低体重指数与高体重指数),形成一个2×3的实验设计。
与对照组和低体重的EDNOS受试者相比,患有BED的个体报告称在负面情绪状态下进食的倾向更大,但与高体重的EDNOS受试者相比则不然。体重并未影响自我报告的对体重和体型的关注。患有BED的个体比无进食障碍的对照组对体重和体型表达出更大的关注。
研究结果表明,应进一步研究对体重和体型的过度关注,将其作为BED的一个诊断特征,并且情绪化进食与BED相关,但与肥胖本身无关。
